The next round stays forty minutes, and the next sixty minutes, after which the mill goes on throughout the week finishing billets, rails, beams, or other shapes at one operation. During a roll change in the finishing mill, the blooming mill may make blooms or large billets, and it is the general practice to have at least two finishing mills supplied from the same blooming mill, and these run alternately so that one is always ready.
